The voluminous La Soledad deposit was erupted in the Zitácuaro-Valle de Bravo volcanic field area about 500,000 years ago and is composed of a complex sequence of block-and-ash and pumice deposits. Geologists in the photo investigate a thick (up to 10 m) pumice deposit that lies on top of a pyroclastic surge layer.
